چکیده

Spin-polarized density functional theory is used to investigate hydrogen-induced magnetism in single-walled carbon nanotubes SWNTs . Hydrogen trapped at a carbon vacancy can trigger delocalized electron spin polarization on semiconducting zigzag SWNTs. Hydrogen pinned by a carbon adatom on the surface of the SWNT can induce spin polarization localized at the carbon adatom, independent of the diameter and chirality of the tube.

Study the stability of Si, Ge, Fe and Co in the interior surface of metallic carbon nanotube for hydrogen storage

In this article, we have performed calculations for studying the stability of the carbon group elements such as Si and Ge and also the magnetic elements like Fe and Co via first principle investigations. We found that Si and Ge decoupled from the interior surface of carbon nanotubes, this fact was independent in curvature, radius, conductivity and numbers of atoms in the carbon nanotubes. But t...

Itinerant flat-band magnetism in hydrogenated carbon nanotubes.

We investigate the electronic and magnetic properties of hydrogenated carbon nanotubes using ab initio spin-polarized calculations within both the local density approximation (LDA) and the generalized gradient approximation (GGA). We find that the combination of charge transfer and carbon network distortion makes the spin-polarized flat-band appear in the tube's energy gap. Various spin-depende...

Radius Dependence of Hydrogen Storage Inside Single Walled Carbon Nanotubes in an Array

In this study, we have investigated radius dependence of hydrogen storage within armchair (n,n) single walled carbon nanotubes (SWCNT) in a square arrays. To this aim, we have employed equilibrium molecular dynamics (MD) simulation. Our simulations results reveal that radius of carbon nanotubes are an important and influent factor in hydrogen distribution inside carbon nanotubes and consequentl...
